Course Description:

S S d d 89 20 fASHRAE Standard 189.1-2011 for High Performance Green Buildings

ASHRAE, in conjunction with the U.S. Green Building Council and the Illumination Engineers Society, has developed a new standard for High Performancedeveloped a new standard for High Performance, Green Buildings (Standard 189.1-2011). The Standard provides the minimum requirements for a hi h f b ildi d d l dhigh-performance green building, and was developed with the intent to provide a balance of environmental factors involved with designing, building, and g g, g,planning for the operation of buildings. This session provides a detailed look at the standard, the background on its development and what is foreseenbackground on its development and what is foreseen for its application and ultimate adoption.
